| The Local Inclusive Photon Polarimeter for RHIC | ||
| Protvino, 2000.-p.17, figs.9, tables 6, refs.:13. | ||
The local inclusive photon polarimeter with full azimuthal coverage is proposed for continuous monitoring of the beam transverse polarizations at RHIC top energy. Since the used beams are mostly longitudinally polarized, the photon detector by measuring the transverse components of the polarization vector is able to determine a stable polarization direction in space. The tracking detector may be used for the vertex reconstruction of photons. For calibration of this polarimeter it is foreseen to install a jet or foil target in the rear part of the main detector, for example, PHENIX. Several sources of backgrounds are revealed and possible ways of their suppressions are discussed. Space limitations and magnetic field of the main experimental setup impose severe restrictions up on the position and shape of the local inclusive photon polarimeter, which were taken into account.
